The victims told police they were in a parked
vehicle near Tennessee's campus when two men, one brandishing a
handgun, approached. The suspects demanded whatever the victims had but
left empty-handed when victims showed they had no money.

The
suspects drove off with a third man in a Toyota Prius. Police located
the car and the victims identified Richardson and Edwards.

Well, at least their getaway was environmentally friendly. From the incident report:

The victims stated that a black male then approached, wearing a
black hoodie, brandished a black semi-auto handgun, opened the drivers
door and stated, 'Give me everything you have.' The victims stated that
a black male then exited from the passenger side of the Prius, wearing
a black hoodie, walked around to the front passenger door of their car,
opened it, and stated, 'Give us everything you've got.'

"The victims stated that they all presented their wallets to the
suspects and showed them that they did not have money. The victims
stated that a third black male then approached and told the other two
black males, "We've got to go." The victims then stated that the three
got into the Prius and that it was last seen traveling southbound on
Volunteer Blvd West.

" ... The victims positively identified Edwards and Richardson as the two who approached their vehicle and demanded everything."

A Volunteer TV News
photographer on the scene captured the suspects while they were being
identified. At least one of them wore a black University of Tennessee
t-shirt with an orange Adidas logo and the phrase "impossible is
nothing."
